RAILWAY-CROSSING.

$PECIFIGATION forming part of Letters Patent No. 571 ,21 5, dated November 10, 1896.

Application filed April 2, 1896. fierial No. 585,937. (No model.)

To all whom it may concern;

Be it known that I, DANIEL COLLEN, of Inwood, in the county of Lambton, Province of Ontario, and Dominion of Canada, have invented a new and Improved Railway-Crossing, of which the following is afull, clear, and exact description.

The object of the invention is to provide a new and improved railway-crossing arranged to provide continuous rails for the easy and safe passage of the wheels of a train and at the same time providing dan ger-signals for ap proaching trains in case the crossing is open.

The invention consists principally of cross ing-rails made slidable for opening and 010s ingthe crossing or diamond.

The invention also consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

' in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement. Fig. 2 is an enlarged plan View of the switch mechanism on one arm of the crossing, and Fig. 3 is a sectional side elevation of the same on the line 3 3 of Fig. 2.

The improved railway-crossing is provided with two tracks A B, of which the track A is provided at the diamond with the fixed railsections A A and the track B is provided with similar fixed rail-sections B B The rail-section A is adapted to be engaged at its ends by slidable rails A A for forming a continuous rail at the crossing, and the fixed railsection A may likewise be abutted at its ends by slidable rails A A The point of the rail A rests on the fixed rail-section A terminating in a switch-point A adapted to com nect with and disconnect from the permanent track-rail A The slidable rail A is adapted to connect at its point with a permanent track rail A and the point of the slidable rail A is in engagement with a fixed rail-section A terminating in a switch-point A adapted to open and close on the permanent track'rail Now it will be seen that when the several parts described are in the position illustrated in Fig. 1 then continuous track-rails for the track A are provided, so that a train can readily pass over the track A, said train having continuous rails for the crossing.

The track 13 is similarly arranged, that is, the rail B in the diamond is adapted to receive at its ends the slidable rails B B and the other rail, B is adapted to receive at its ends the slidable rails and B The slidable rail B engages with its point the permanent rail-section B terminating in its outer end in a switch-point B adapted to open and close on the permanent track-rail B". The slidable rail 13" is adapted to engage with its point the permanent track-rail B and the slidable rail B is adapted to engage with its point the permanent track-rail B The slid able rail B is adapted to engage with its point the permanent rail-section B terminating at its outer end in a switch-point B adapted to open and close on the permanent trackrail B Now in order to move the movable parts of the tracks A and B for opening or closing either of the tracks at the crossing I provide the following mechanism for each track, said mechanism being under the control of the operator located in a tower near the crossing: Under the track A is arranged a transverse shaft 0, and a similar, shaft 0 is arranged under the track B, and both shafts can be operated by the operator in the tower. 0n the shaft 0 are secured the double arms D D, connected by rods E E, respectively, with the outer ends of a bar F, carrying the inner ends of the slidable rails A A Similar rods E E extend from the arms D D to connect with a bar F, carrying the ends of the slidable rails A A. '1 bus When the slidable rails A? A A A are in an innermost or closed po sition, as shown in Fig. 1, that is, abutting on the permanent rail-sections A A and the operator turns the shaft 0, then the arms D D impart simultaneously a sliding motion to the bars F F, so that the slidable rail-sections are moved longitudinally away from the permanent sections A A In doing so the outer point ends of said slidable rail-sections A A and A A move out of alinement with the rail-sections A A A, and A respectively, and consequently the rails of the track A are not continuous at the crossing. XV hen the shaft 0 is then again turned in the opposite direction, the slidable rail-sections move inward to again form continuous track-rails at the crossing, as shown in Fig. 1.

In order to hold the points of the slidable rail-sections A A and A A in proper rela tion to the fixed rail-sections above mentioned at the time the track is continuous, I provide arms G G, which extend from the bar F and carry blocks G G adapted to engage the outer ends of the slidable rail-sections A A said arms G being pivotally connected with links H II, respectively fulcrumed in the rail-sections A A respectively. Nowit will be seen that when the bar F moves outward the arms G G are swung inwardly to permit the points of the slidable rails A A to move inward, and when the tie F moves back to its former position then the arms G G swing outwardly and their blocks G G rest against the inner sides of the slidable rails to bring their points again in proper alinement with the permanent rails A A A similar arrangement is made on the other arm of the track A, in that the bar F is pivotally connected by arms G G with links H H respectively fulcrumed on the track-rails A and A, respectively. Blocks G6 G are held on the arms G and G to engage the inner sides of the slidable rails A A and press the latter in contact with the fixed rail-sections A A to form a continuous track with the same. Thus the blocks serve as looking devices for the slidable rails to hold the latter in alinement with the adjacent permanent rail-sections.

In order to operate the switch-point A I pivotally connect the same near its free end with a transversely-extending link I, pivotally connected with a link I, engaged by the slotted end of a link J, pivoted to the tie F. WVhen the latter moves outward, as previously described, then the link J imparts a swinging motion to the link I, and the latter moves the link I transversely, so that the switch A is thrown into an open position at the time the slidable rails A A disconnect from the permanent rail-sections A A The outer end of the link J is pivotally connected with a link J fulcrumed on one of the ties, and said link J is also pivotally c011- nected with a link K, carrying a signal L, the said link K being pivotally connected with a link K, fulcrumed on one of the ties. When the bar F moves outward, as previously described, then the signal L is shifted and set to a dangerposition, to warn a train approaching the crossing on the track A in the direc tion of the arrow at that the track is open at the crossing.

The switch-point A is pivotally connected near its free end with a transversely-extending link 1 connected with a link 1 operated from a link J pivoted on the tie F, said link J 2 being also connected with a link K carrying a signal similar to the one on the link K. The link K is controlled bya link K pivoted on one of the ties.

Then the bar F moves outward simultadeemed necessary.

neously with the bar F, as previously explained, then the switch-point A is swung away from the permanent track-rail A at the same time the signal L on the link K is set at danger, so that a train approaching the crossing on the track A in the direction of the arrow b is warned of the danger, as the track is open at the crossing. The same arrangement as in reference to the track A is made 011 the track B for moving the slidable rails 13 B and B B inward or outward from ties F F respectively connected by links E, E E and E respectively, with double arms D D on the shaft 0'.

The switch-points 13 and B are actuated from the bars F F in the same manner as the switch-points A A are operated from the bars F F, respectively, and consequently further description of this mechanism is not Furthermore, the slidable rails B 13 and B B are locked in place when closed by blocks similar to the blocks 13 B B B previously described in reference to the slidable rails A A A A, the only difference being that those blocks for the slidable rails B B and B B are actuated from the bars F F The signals L (see Figs. 2 and 3) are arranged at the approaches of the track 13 to the crossing, so as to warn approaching trains on the track B in case there is danger, or to give the said train the signal that the track is continuous over the crossing.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1.
